可以說糾結了不少時間了
用mvn archetyoe:generate 時總是會出現以下的情況：
正常的應該是
$ mvn archetype:generate
[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: 'archetype'.
[INFO] ------------------------------------------------------------------------

2: internal -> appfuse-basic-spring (AppFuse archetype for creating a web application with Hibernate, Spring and Spring MVC)
...........
internal -> maven-archetype-sar (JBoss Service Archive)
36: internal -> wicket-archetype-quickstart (A simple Apache Wicket project)
Choose a number: (1/2/3/4/5/6/7/8/9/10/11/12/13/14/15/16/17/18/19/20/21/22/23/24/25/26/27/28/29/30/31/32/33/34/35/36): 15
....
以前使用一直正常（有一段時間了）
可現在無論在哪臺機器上都是這樣的情況：
[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: 'archetype'.
[INFO] ------------------------------------------------------------------------
[INFO] Building Maven Default Project
[INFO] task-segment: [archetype:generate] (aggregator-style)

....
居然是這樣，到了290了....
而且choose a nubmer 默認寫了個80不知道啥意思..... 選以前的web項目(18) 不管用還是繼續讓我choose version
最後發現可以choose的version 只有 1 和2 ..
根本沒有普通java項目和web項目
咋回事兒？
後來找到了解決方案：
方案1：繞行
mvn archetype:create -DgroupId=[your group id] -DartifactId=[your archetype id] -DarchetypeArtifactId=maven-archetype-webapp
方案2 ： 謝謝，juvenshun 大哥的幫助。（引用）:
可以使用 $mvn archetype:generate -DarchetypeCatalog=internal
archetypeCatalog表示插件使用的archetype元數據，默認值爲remote,local，即中央倉庫archetype元數據（http://repo1.maven.org/maven2/archetype-catalog.xml）加上插件內置元數據的和
由於中央倉庫的archetype太多，導致這個列表太長
因此自己指定僅用內置元數據（20個左右，好像），就可以解決你的煩惱了
